He didn’t say he wouldn’t run for POTUS in the debates.
Because he didn’t say anything *at all* about his aspirations in the debates. What a ballsy, call it like it is guy! Not. That’s why he’s not presidential material.
But when he ran for a 2nd term as Florida’s governor he was making an implicit promise to Floridians that he’d stay the course.
And now he should.
